Not that I can tell. I don't legally require glasses (20/40 vision), but have owned light prescription glasses that i've worn on certain occasions such as driving at night or seeing from the back of a classroom. In the past 10 years i haven't noticed any change.

They say wearing them doesn't make your vision worse, but I know it is tougher to see the same things without them than before I got them. I have moderate astigmatism that wasn't diagnosed until I was 25, but I had managed to function pretty well up to that point despite not being able to discern much detail. Once I had worn glasses for a few weeks, I was practically blind once I took them off. Even now, I can't do a lot of things with them off that I used to be able to do just fine before I got them. I can only assume that my eyes have acclimated to having the correction all the time and don't work as hard without it any more.

I have a 1.5 correction or so on my eyes (thats not that bad, but I don't know the conversion). I was also diagnosed "later" (around 16/17) and didn't really wear glasses/contacts regularly until a few years ago (28 or so).

Mine haven't gotten significantly worse, but I agree that if you wear them for long periods and then don't...shit gets real. I ran out of contacts after a year of wearing them and have only been wearing glasses to drive lately though and I still feel functional without them (unlike Fender). I think it isn't so much that it is worse, but you just notice it more.

If the glasses are smudged they will make your vision worse, but if you clean them well it will go away

I saw this as "Dogs wearing glasses...."

It's a hard thing to test experimentally, and eye doctors seem to say "no" they don't, but anecdotally I feel enough people say "yes" that there is something to that.

It seems like it's the same as any muscle. When you have glasses do the work for your eyes, they slack off and have a harder time when they're asked to see unassisted. But when they're on their own for a while, they get used to the demands placed on them again to a certain extent. So while wearing glasses might not make your vision actually worse per se, it makes your eyes lazier in the short term. There's my anecdotal theory that I just pulled out of my ass.

I have a -4.00 correction and cannot see squat at any distance greater than about a foot without my glasses. But I see just fine to read without glasses, so whenever I read I do so without my glasses. I wore contacts until a few years ago, so obviously I read with my contacts in. Well in the few years I've read without correction, I've had a slight (.25) improvement in my vision. My doctor credits all of the reading without correction for strengthening my eyes. So I don't think glasses hurt your vision, but they don't really do anything to improve what you've got.

I started wearing glasses when I was ~8 and switched to contacts at 15. My vision got worse almost every year until maybe my 2nd year in college. I'm at a -6.00 now at 35, and have been steady for about 15 years now.

i'm no ophthalmologist, but I suspect the worsening over time is the natural progression of myopia, rather than being caused by glasses/corrective optics. It's easy to blame the glasses though, since people will certainly seek correction at the earlier stages of nearsightedness.

to add to my earlier comments, i used the same glasses from 16-28. when they broke i finally looked into contacts. so my answer would be...no.

My doc said that your vision changes until you're in your early 20s and then remains fairly stable until you reach old age.

people who wear glasses tend to have poor vision, so therefore logically they do.

The eye and the brain can get used to incredible changes in lenses, and there's been many experiments to that effect, even with lenses that rotate and flip the field of vision. so if you get a bad prescription (as the exam is ultimately subjective and variable depending on how you answer the final adjustment questions, even with more reliance on extrapolation from eye measurements), Your eye will get used to it, and if you were to habitually get judged as needing a stronger and stronger prescription, your eyes will adjust and get weaker. So, don't keep going back to a bad doctor.

One of my eyes got somewhat (by less than +.25) better after years and years of wearing the same prescription. The doctor bumped me to the next level in contacts. Initially I preferred being over-corrected than under-corrected, and thought the new prescription was too weak. But now I've worn that prescription for a year and habituated to that, so the old lens that was a bit stronger feels too strong.

When I had one eye start worsening and getting lazy the doctor lowered the prescription in the other eye so the lazy one would have to work harder. It worked. No more lazy eye and the worsening stopped.
